Therapieoptionen bei Basalzellkarzinomen des medialen Lidwinkels

Abstract

Basal cell carcinoma is the most common skin cancer of the eyelid. It most frequently occurs on the lower eyelid and the medial canthus. Although metastases appear only very rarely, basal cell carcinoma is locally destructive if left untreated. Nowadays several surgical and nonsurgical treatments can be used to remove or destroy basal cell carcinomas. The selection of optimal treatment depends on the initial individual situation as well as the age and the general condition of the patient. The "gold standard" method for the treatment of basal cell carcinomas is surgical removal with subsequent histological examination. Because of the complex anatomical characteristics of the medial canthus and the lateral nasal root region, basal cell carcinomas of this area present great challenges for any treatment method. These characteristics also explain the higher rates of incomplete removal and greater risk of recurrence, with in depth extension of the tumor. Additionally, surgical removal of the tumor from the medial canthus area often results in extended tissue defects. The plastic covering of these defects can be achieved by various reconstruction procedures.
